| Abstract: | This article describes the procedure calculation of the little curved radius tubular semifinished product such as ductility, intensity, etc. Sequently it select apporpriate procedure programe, especially should properly choose the stuffing, in order to estaflish rational stresses situation and improve the moterial plasticity. Then the article recommends to adopt the stuffing of low melting point alloy and full-close extruding currature procedure. It also supplys and confers a series of caculation formula in case of caculating procedure parameters for reference. Finally the article look into the future the procedure developing tendency of the little-curved radius tubular semifinished product. |
